Rootstock simple or none. Stem produclni^ very short decumbent 

 barren shoots and rather short ascending flowering shoots. Lower 

 leaves oblanceolate, much attenuated towards the base ; the upper 

 ones obovate-oblong or oval, all imbricated, sub-sessile, acute, 

 1-nerved when dry, fleshy, smooth and glabrous except that occa- 

 sionally there are a few hairs on the margins. Tlowers few, in 

 dichotomous cymes (frequently reduced to 1 or 2 flowers) ter- 

 minating the stem and branches, with ovate or lanceolate leaf-like 

 bracts. Pedicels equalling or slightly exceeding the sepals, erect. 

 Sepals triangular-ovate, acute, with 3 ill-defined glabrous nerves 

 down the middle ; the lateral ones often scarcely perceptible ; the 

 margins very narrowly membranous and glabrous. Petals oblanceo- 

 late, exceeding the sepals by about half their length. Caj)sule ovate- 

 ovoid, about as long as the sepals. Seeds roundish-reniform, coarsely 

 shagreened. Plant glabrous, except the upper part of the stem and 

 peduncles, which have short hairs, some of them gland-tipped. 



On loose gravel. Very rare. On the gravel of a serpentine hill 

 immediately to the Xorth of Baltasound, Unst, Shetland, where it

 North Ronaldshay. 



Scotland. Perennial or Annual ? Summer and Autumn.

 the base into numerous equal divisions, which are 1 to 3 inches 

 high. Leaves closely placed, i to ^ inch long, increasing in size 

 from the base of the stem to the commencement of the cyme ; when 

 fresh appearing nerveless, but showing a rather indistinct midrib 

 when dry. Plowers f inch across, white. Seeds roundish reniform.
